This is a right side (drive) replacement insert for all of our flat or flanged sliding dropouts and is compatible with the Shimano E-Thru 12 mm skewer only. It is made from black anodized 6061 aluminum and has a derailleur hanger for multi-speed applications. The center of the axle to the center of the derailleur bolt is 1.180".
Included is a 14 mm long retainer and M4 x 8 mm button head cap screw that hold the Shimano nut captive. There are
nine notches in the retainer that index the notches on the nut. This allows
the closed position of the skewer to be adjusted every 40 degrees for
optimal location. If none of these positions work, the retainer can be
flipped over to utilize nine more positions that are 20 degrees out of
phase from the original positions.
Note: Frames built for 135 x 10 mm spacing can use this insert with a 142 x 12 mm skewer (nothing wider).
Options (from pull down menu above):
1) Shimano 142, 157, 177, and 198 x 12 mm skewer.
